Do we have any proof that J wasn't talking about worker drones? I mean, the quote was "Effective drones were cloned more." Was there something I missed?
Counterpoint if effective drones were cloned was referring to worker drones, why are there not clones of dead drones? And why would you think J would be talking about them?
Disassembly drones are just modded worker drones. It's not that far of a stretch to suggest that if a company has one good thing, they want to make it into two or more good things. Especially since all they would really have to do is copy and paste the code into a new body. (also see the theory that Uzi is a clone of Nori. Sounds crazy but it's actually kinda plausible.)
